COVID-19 is the most devastating plague to ravage humankind this century. Every day, the number of patients infected with the coronavirus is rising globally and taking the highest human toll in the United States. The highly infectious virus was first contracted in November 2019 in Wuhan, the capital city of China’s Hubei province, through horseshoe bat-to-human contact at the Huanan seafood market.
Many of the initial COVID-19 patients were either stall owners, market employees or regular visitors of the market, who rapidly developed a severe respiratory illness. Despite the market being shut down on Jan. 1, 2020, the virus has since rapidly spread airborne during exhalation, talking and coughing via microdroplets small enough to remain aloft in air, spreading to over 200 countries and regions around the world.
